consequences II

• Temperature


  Measure of the hotness or coldness of an object, corresponds to the kinetic energy of the molecules
• Heat


  Flow of energy from one object to another due to temperature differences
• Energy cannot be created nor destroyed, it can only be transformed from one type to another
• Heat will always flow spontaneously from objects with higher temperature to those with lower temperature unless acted upon by an external force
• Heat flow


  From higher temperature to lower temperature
• Phase


  • Physically distinctive form of matter that classifies it as solid, liquid, or gas
• Melting


  Solid to liquid phase change due to heat absorption (endothermic)
• Evaporation


  Liquid to gas phase change due to heat absorption (endothermic)
• Condensation


  Gas to liquid phase change due to heat release (exothermic)
• Freezing


  Liquid to solid phase change due to heat release (exothermic)
• Deposition


  Gas to solid phase change due to heat release (exothermic)
• Sublimation


  Solid to gas phase change due to heat absorption (endothermic)
• When heat flows into matter- (endothermic)
• When heat flows out of matter- (exothermic)
